An object of the present invention is to provide an improved arrangementfor disposing of the moisture from the evaporating element of arefrigerating system. I

Another object of the present invention is to arrangefor the drainage ofthe drip moisture from a collecting tray to a vessel located in a secondcompartment provided in a cabinet whereby the arrangement is such as notto interfere with a ready withdrawal of the tray or the ordinaryintended use of the second compartment.-

The invention itself, however, both as to its organization, and itsmethod of operation together with additional objects and advantagesthereof, will best be understood from the following description ofspecific embodiments when read in conjunction with the accompanyingdrawing in which:

.Fig. 1 is a central vertical cross-sectional view of a refrigeratorcabinet showing the invention applied; and

Fig. 2 is a fragmentary cross-sectional view taken along line {-2 ofFig. 1.

.In the drawing there is'shown a cabinet I! having insulated, top.bottom and side walls I! enclosing a food storage compartment I. liecessto compartment I4 is through opening it, provided in the front wall ofthe cabinet, which is closed by a swingably mounted closure memplisliedautomatically at periodical intervals,

whereas in other types the defrosting is accomplished by a manualsetting of the thermostatic controls as is'well understood in the art.The

present invention is adapted be used with either type of evaporator.

Positioned beneath the evaporator 30 to catch the drip therefrom duringdefrosting is a shallow tray 40 which is supportedon and serves as acover for a deep tray 42. The tray 42 is-retractably supported on rails44 of shelf 45 supported onlugs ll projecting outwardly from the wallsof compartment ll. Secured to the rear wall of tray 40 so as to drainthe contents of the tray is one end of tube 41. the other end terminating over and above a funnel shaped opening 40 of tube to.

Projecting into compartment and aihxed to closure member 24 to become apart thereof is an open receptacle or bin 52 used for the storage offoods which can be safely kept at relatively high temperature as isfound in the machine compartment 20. Suspended from studs 59 secured toa wall of the bin 52 is an open container 2 W adapted to receive thewater collected in tray her II. A second compartment 20 is providedbeneath compartment It and insulated therefrom. The compartment 20 hasan opening 22 in the front wall of the cabinet and is closed by closuremember 24 that is swingably mounted by arcuate plates 26 projectingthrough and oper- Secured to the top wall of compartment M' is anevaporator 30 connected by conduits BI and" 32 to a hermetically sealedmotor-compressor andcondensing element 33 positioned in compartment 2!.The heat laden refrigerant is withdrawn from the evaporator 30 throughconduit 32 into the motor-compressor unit 34 where it is comative inslots 28 formed in rail 21 of the cabinet 1 40 and conveyed througn'tubeto. End SI of tube to terminates over and above the bin 52 positioned sothat the water will flow directly into the container 60. The containerto is provided with bayonet slots 62 for receiving the studs 59permitting a ready removal or replacement of the container 80. 1 a

It will be noted that the arrangement of the drainage conduit is suchthat it does not interfere with the ordinary use of the refrigerator.That is, the trays 42 and 40 are readily retractable on its guide rails44, or may be bodily removed from the refrigerator without necessitatingany attention for the breaking of the drainage connection. The drainageconnection of tray 40 with tube 50 being remade by placing the tray inits normal position beneath the evaporator. Similarly the free or normaluse of thebin 52 is not interfered with by any direct 45 conduitconnection requiring the user's attention.

. pressed and from whence it is delivered into con- To prevent the rearwall of the bin 62 from becoming excessively heated due to its proximateposition near the compressor condenser unit 21 and thereby heat up thefood stored in the bin 51 a pad of heat insulation 65 is afllxed to theexterior surface of the.rear wall of bin 52.

While these illustrated and described the preferred form of myinvention, I do not wish to limit myself to the precise details as shown55 but wish to avail myself of such variations and positioned m 58.1
